GENERAL DESCRIPTION
The EM91450 is a series of tone/pulse switchable dialers that is composed of T/P dialer. The EM91465 provide
modern LCD driver's series data output port, which can display modern function operating icons. The
EM91450 series provide necessary functions of telephone set for application in any environment, such as Pulse
dialing, Tone (DTMF) dialing, Handfree dialing, keying tone ,and lock functions. The lock function is designed
to inhibit toll dialing operation. Beside this, ring detector and SDO (Serial Data Output) functions are provided
in advance version. Ring detector can prevent illegal dialing from pocket dialer. The SDO is designed to drive
LCD driver and voice synthesizer. In this application, the dialing numbers and modern function operating icons
can be displayed on LCD screen with LCD driver (EM32100 or EM32117 ). The EM91450 has a special I.P.
P. detect function (Illegal Parallel Phone Detect) can prevent the illegal connect external Phone. The I.P.P. will
detect the illegal user. When illegal user pickup phone, the function will alarm and send the alarm signal to the
telephone line to interfer the illegal dialing.
FEATURES
I.P.P. detect function prevents the illegal connect external phone.
SDO function supports LCD driver and voice synthesizer to indicate dialing numbers and function operat
ing icons.
Lock function provides conventionality key lock and password lock operations.
Ring detector is designed to prevent illegal dialing from pocket dialer.
Line hold function is designed for stopping conversation temporality.

Low operating current, 0.15 mA (Pulse) and 0.3 mA (Tone) typically.
Adding resistor on keyboard scan pin that can select many telephone specifications, such as : Pulse rate,
M/B ratio, Flash time, lock dialing functions.
13 set one touch or (3 set one touch and 10 set two touch) repertory memory, each one can hold data up to
16 digits.
A 32-digit LNB (last number) redial memory.
Keytone function provides rapidly keying recognition.
